Formation of required distributions on the basis of decomposition by vortex eigen functions of a bounded non-paraxial propagation operator [PDF]
Компьютерная оптика, 2019 The solution of the problem of overcoming the diffraction limit based on the representation of an optical signal in the form of a superposition of communication modes matched with the vortex eigenfunctions of a bounded (in the object and spectral regions)

Topological and iterated structures of the superposition operator on Fock spaces
The Journal of AnalysisWe characterize various topological structures of the weighted superposition operator on Fock spaces. The global homeomorphism property of the operator is described by its ray-invertibility condition. We further consider its iterated structures and prove

Shell Model Monte Carlo Methods [PDF]
, 1996 We review quantum Monte Carlo methods for dealing with large shell model problems. These methods reduce the imaginary-time many-body evolution operator to a coherent superposition of one-body evolutions in fluctuating one-body fields; the resultant path ...

Quantum information transport to multiple receivers
, 2005 The importance of transporting quantum information and entanglement with high fidelity cannot be overemphasized. We present a scheme based on adiabatic passage that allows for transportation of a qubit, operator measurements and entanglement, using a 1-D

Superpositions for nonlinear operators. I. Strong superpositions and linearizability
Journal of Mathematical Analysis and Applications, 1972 AbstractA notion of superposition for nonlinear operators is defined and strong and weak superpositions are distinguished. The classification and representation of operators having a strong superposition is treated. The algebra induced by the superposition on the domain of operators with strong superpositions, as well as their relation to linearizable ...

Macroscopicity of quantum superpositions on a one-parameter unitary path in Hilbert space [PDF]
, 2014 We analyze quantum states formed as superpositions of an initial pure product state and its image under local unitary evolution, using two measurement-based measures of superposition size: one based on the optimal quantum binary distinguishability of the

Quantum Power Method by a Superposition of Time-Evolved States [PDF]
, 2020 We propose a quantum-classical hybrid algorithm of the power method, here dubbed as quantum power method, to evaluate $\hat{\mathcal{H}}^{n}|\psi\rangle$ with quantum computers, where $n$ is a nonnegative integer, $\hat{\mathcal{H}}$ is a time ...

Measurement- and comparison-based sizes of Schrödinger cat states of light [PDF]
, 2014 We extend several measurement-based definitions of effective superposition size to coherent state superpositions with branches composed of either single coherent states or tensor products of coherent states. These measures of superposition size depend on

Superposition operator problems of Hölder-Lipschitz spaces
Demonstratio MathematicaLet ff be a function defined on the real line, and Tf{T}_{f} be the corresponding superposition operator which maps hh to Tf(h){T}_{f}\left(h), i.e., Tf(h)=f∘h{T}_{f}\left(h)=f\circ h. In this article, the sufficient and necessary conditions such that Tf{
